Explanation / Answer

1. You need to declare 3 strings variable. 2. Ask user to input the 3 names. 3. Use compareTo to compare strings. Youcannot use = = . 4. So when str1.compareTo(str2) > 0means that the alphabetical order of first string is larger thansecond string,     therefore we swap their position. 5. We have to compare 3 sets, which are 1st name & 2nd name,1st name & 3rd name, 2nd name & 3rd name. 6. So, if str1 is greater than str2, do temp=str1; the variable str1 shouldstore str2, therefore we save value of str1 into another temporaryvariable, which is temp. 7. Next, we save value of str2 into str1, which is str1=str2; 8. Lastly, weput back value of str1 which is in temp into str2 by str2=temp; 9. Forexample, let str1 be Belinda and str2 be Alex.    After temp=str1; str1=str2; str2=temp; their positionare being swapped and the output will be str1=Alex andstr2=Belinda
